oooobooo 0000050000000 Patented Oct. 21, 1930 EoBEET T. CAMERON, orMEMPHIS, TENNESSEE COFFEE PEEcoLATon Application led February 17, 1930.'Serial No.,429, 114.

' The ordinary coffee percolator isvvasteful diameter than the strainercup', 11. The cup,

of coffee and otherwise ineicient because the by Which it may be slippedover the verticall tube, 12, concentric With the latter and Withv groundcoifeecapacity of the perforated cup is much greater than the ordinaryyrequirements. This results in considerable quantity of ground coffeebeing beyond the reach oi r1 the descending streams of leachingl Water,

and thus is not utilized. The object of, my invention is to remedy thisand todo so by means at oncesimple and rinexpensive and which Willenable the full capacity of the large capacity percolator to beutilized-vvhen desired. An important'feature ofmyginven'- tion isthat'it involves no .structural alteration Whatever inthe ordinarypercolatoron' the market today; My invention .consists in scribed by oris included Within scope of the appended claims.

In the -draWings The ligure is a vertical i percolator embodying myinvention, Thepercolator shown is of the ordinary construction'thatincludes a pot, V10; lstrainer section of Va'icolee Whatever the termsvor 14', hasfin its bottom at thecenter a hole, 15,'

themain strainercup, 11, and just as readily 55 removed. 1t Will beevident that thesupplemental cup, 14, Will confine the coiee grounds,close'to the tube, 12, and With considerable depth-y and Within thezone or regiony Where the greatestr quantity of drippings descend -60`from the domal.V v I The supplementi cup, 14, mayl be left in placeWhen a `larger quantitythan its vcapaci-A tv is to be used because thelarger quantity can-'be vplaced in thexa'nnular space between,v 65

v`thetvvo.cupsas Well aswithin the supple- 'l mental cup, 14.

It Will be seen that-'my percolatoris'lchar- ,I

vacterized by a Vstrainer cup Whichk isl of therr 5 .diameter of theinterior of thecoiee pot and 70 i .which may be termedrthe main strainercup:

anda supplementalstrainer cup Within and@ concentric With the main cupand of substantiallylessdiameter than the latter so that or drip cup,11; a vertical hot Water ascendf y ing tube, 12, Whichreaches'from thepot bottom to the top; and the .Water distributing dome, 13,Y usuallyof` glass'ivvhich receives Water issuing from the tube top and causes itto fall in drops or streamsupon coffee the strainer cup, 11. v f' f Thecup, 11, if of a diameter to InakeffourV cups of coffee is so large thatif ground coffee'v of a quantity to makeonly two cups is placed therein'and reaches yto the side Walls of the strainer cup, the depthofzgrounds-Will be an annular space exists between the side .Walls 75 1l* ofthe tWo cups.
